Abstract
PURPOSE: To accurately measure the minute flowing speed and direction of ground water by constructing to transmit the ground water stream energy to a float and operating needle and to pressurize the actuation needle at a predetermined position of the float.
CONSTITUTION: A measuring hole B reaching a permeating water layer A is bored, a casing C perforated with a number of pores is inserted into the hole B, and a device body for measuring ground water flowing state is lowered while sequentially extending the connecting rods 21 thereto. When a vertical tube 3 of the body enters into the layer A, a float 5 is raised along an operating needle 4, so that the floating position of the float 5 is retained at a stabled position. When the tube 3 is slowly rotated in this state, the water stream energy is transmitted to the float and when the rocking direction of the needle 4 comes to coincide with the water stream direction E, the needle of an instrument 24 which is set on the ground fluctuates at the maximum, and the flowing speed and direction of the ground water stream are indicated thereby.
